Terragrunt Validator

This is your go-to when you need to validate Terragrunt configurations without manually running a dozen commands. It bundles HCL formatting checks, input validation, linting with tflint, security scanning with Trivy, and dry-run planning into one script you can run in CI or locally. Built for Terragrunt 0.93+ with the new CLI (so `run --all` instead of `run-all`). The standout feature is the custom provider and module detection script that identifies non-HashiCorp providers and remote modules, then tells you exactly how to look up their docs using Context7 MCP or web search. Useful when you inherit a Terragrunt setup and need to understand what third-party dependencies are lurking in there.

Terragrunt Validator

Overview

This skill provides comprehensive validation, linting, and testing capabilities for Terragrunt configurations. Terragrunt is a thin wrapper for Terraform/OpenTofu that provides extra tools for keeping configurations DRY (Don't Repeat Yourself), working with multiple modules, and managing remote state.

Use this skill when:

Validating Terragrunt HCL files (*.hcl, terragrunt.hcl, terragrunt.stack.hcl)
Working with Terragrunt Stacks (unit/stack blocks, terragrunt stack generate/run)
Performing dry-run testing with terragrunt plan
Linting Terragrunt/Terraform code for best practices
Detecting and researching custom providers or modules
Debugging Terragrunt configuration issues
Checking dependency graphs
Formatting HCL files
Running security scans on infrastructure code (Trivy, Checkov)
Generating run reports and summaries
